"Furnace in my home stopped working. Went through Home Advisor and had one company come over. They had stated that I needed a new furnace.Scott had called and came over within 1 hour, checked my furnace and found that it was plugged. He did the repairs and running great again. This is the second time he had done work for me a year ago on my air conditioning unit.He does great work, honest and his prices are fair. I will not rely on anyone else, except for Scott. He is my permanent repair man."

"Mamayek Heating was very proficient with their installation of whole house central air-conditioning in our 1896 year-old home which never had a unit in place. From start to finish, they accommodated our needs and schedule as well as leaving behind a nicely done project in working order. Thank you to the 3 Bobs for all their help!"

"The install took longer than expected because they are a small company, and were extra busy with other jobs that week. However, when it was all said and done, I am quite pleased with the results. The AC works great in the summer, and my winter heating bills are almost 50% less than they used to be. Would I do it again? Yes. Would I wait this long to do it? No Way! One of the main reasons Bob's company is special is that he does a good portion of the work himself. It's not contracted out to people you don't know. You meet Bob, and he does the work. Bob was also very accommodating about where to place vents, how to route ducts, etc... He also did a good job at educating me on how the system works along the way. Thanks Bob!"

"My technician Kyle was very informative and respectful. He explained what was going on and was very professional. Kyle even left me with an electric heater for the evening until they could replace my furnace the next day. Kyle was back early the next morning to start the replacement of my old furnace for the new one and it is working great! I am so happy that I was able to get this done right away."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

FAQs for air conditioning projects in Greenfield, WI

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
